Description

Technical Field

[0001] This utility model relates to the field of civil engineering testing equipment technology, specifically to a deflection testing auxiliary device. Background Technology

[0002] Deflection refers to the bending deformation of a building or bridge structure (component) under load, directly reflecting the mechanical performance and working state of the structure. Therefore, accurate detection of the deflection of structural components or the entire structure under applied load is crucial for assessing the stress state and overall safety of the structure (component). Currently, the dial gauge (or micrometer, displacement gauge) method is one of the commonly used methods for structural (component) deflection testing. Its working principle is to directly measure the deformation of the structure (component) under load by installing a dial gauge or similar device at the bottom of the part to be measured.

[0003] On-site testing typically involves fixing hooks to the bottom of the structure (component), connecting steel wires, and attaching a plumb bob to the other end of the wires. The plumb bob is pulled by the steel wires to transfer the deformation of the structure (component) downwards. By placing iron discs and magnetic bases on the ground, the dial indicator probe is fixed in the groove at the bottom of the plumb bob, thereby enabling accurate measurement of the structure's deflection using a dial indicator and related equipment on the ground.

[0004] In actual testing, the testing device mainly consists of a plumb bob, magnetic base, iron disc, steel wire, and dial indicator. On the one hand, due to the large number of components, the assembly and storage process is quite complex, and on-site assembly is time-consuming and labor-intensive. On the other hand, the testing device does not have a fine steel wire storage device, and on-site testing personnel generally use manual storage. However, manual storage of fine steel wire easily causes the wire coils to become tangled and knotted, making the steel wire unusable and wasting resources to some extent. Utility Model Content

[0005] In view of the above problems, this utility model provides a deflection detection auxiliary device to solve the problems of complex assembly, cumbersome operation and difficult storage of existing deflection detection equipment.

[0006] To achieve the above objectives, the applicant provides a deflection detection auxiliary device, including a pull-down mechanism and a support mechanism. The pull-down mechanism includes a first gravity member, a second gravity member, and a pull-down component. The second gravity member is disposed inside the first gravity member and is rotatably connected to the first gravity member. The pull-down component is disposed inside the first gravity member, with one end penetrating the inner wall of the first gravity member and extending to the outer surface of the first gravity member. The pull-down mechanism is used to guide the deformation of the component to be tested under external load to a lower position for easy detection. The support mechanism is disposed on the second gravity member and is used to lift the dial indicator off the ground.

[0007] Preferably, the first gravity component is a steel ring, and the second gravity component is a steel disk.

[0008] Preferably, the device further includes a turntable and an elastic element. The turntable is rotatably disposed inside the first gravity element, the elastic element is disposed on the inner side of the turntable, and the pull-down element is disposed on the outer side of the turntable. One end of the elastic element is connected to the first gravity element, and the other end of the elastic element penetrates through the inner wall of the turntable and is connected to the other end of the pull-down element.

[0009] Preferably, the pull-down member is a steel wire rope, and the elastic member is a spiral spring.

[0010] Preferably, the support mechanism includes a folding bracket and a first clamp. The second gravity member is provided with a receiving groove. The folding bracket and the first clamp are received in the receiving groove. One end of the folding bracket is rotatably connected to the inner wall of the receiving groove, and the other end of the folding bracket is fixedly connected to the first clamp. The folding bracket is used to lift the dial indicator off the ground, and the first clamp is used to fix the dial indicator.

[0011] Preferably, the device further includes a locking assembly, which includes a rotating bolt, a fixed column, and a second clamp. The fixed column is fixed to the top of the first gravity member, and the second clamp is disposed inside the fixed column. The rotating bolt is threadedly connected to the fixed column, and the inner wall of the rotating bolt abuts against the outer wall of the second clamp.

[0012] Preferably, the second gravity component is provided with a rotating shaft, and the first gravity component is provided with a shaft hole adapted to the rotating shaft.

[0013] Preferably, it further includes a limiting component, which includes a limiting outer frame and a limiting block. The limiting outer frame is disposed on the side wall of the first gravity member, and the limiting block is disposed on the inner side of the limiting outer frame, and the limiting block is slidably connected to the limiting outer frame.

[0014] Preferably, the bottom of the first gravity member is provided with a groove.

[0015] Preferably, it also includes a pull ring, which is connected to one end of the pull-down member.

[0016] Unlike existing technologies, the above-mentioned technical solution has the following advantages: The pull-down mechanism in this utility model generates tension through its own weight, which can draw the deformation of the component under test under external load to a lower position for easy detection. The support mechanism provides reliable support for the dial indicator, improving the efficiency of the test. At the same time, the pull-down component is set inside the first gravity component, and the support mechanism is set on the second gravity component. When it is necessary to detect the deflection of the component under test, only the two deflection detection auxiliary devices need to be used together, eliminating the need for complicated assembly and storage after the test, making the deflection detection more convenient and efficient.

[0037] Please see Figures 1 to 6This embodiment provides a deflection detection auxiliary device, including a pull-down mechanism and a support mechanism. The pull-down mechanism includes a first gravity member 1, a second gravity member 4, and a pull-down member 11. The second gravity member 4 is disposed inside the first gravity member 1 and is rotatably connected to the first gravity member 1. The pull-down member 11 is disposed inside the first gravity member 1, and one end of the pull-down member 11 penetrates the inner wall of the first gravity member 1 and extends to the outer surface of the first gravity member 1. The pull-down mechanism is used to guide the deformation of the component to be tested under external load to a lower position for easy detection. The support mechanism is disposed on the second gravity member 4 and is used to lift the dial indicator 9 off the ground.

[0038] The pull-down mechanism is a key component for realizing the core function of this device. It consists of three main parts: a first gravity component 1 serving as the basic support, a rotatable and adjustable second gravity component 4, and a pull-down component 11 that directly transmits deformation. Its core function is to guide the deformation of the component under test under external load to a lower position, providing the basic conditions for deflection detection.

[0039] The first gravity component 1 is a main structure made of high-density metal material, with sufficient weight and structural strength. It serves as the base of the entire device, providing an installation reference for other components. At the same time, the device's own weight ensures that the pull-down component is tensioned and straightened, avoiding the impact of device displacement on detection accuracy.

[0040] The second gravity component 4 is a rotating part installed inside the first gravity component 1, and it is also made of high-density metal material. The second gravity component 4 and the first gravity component 1 form a rotational engagement, which can provide part of the downward gravity together with the first gravity component 1. At the same time, after the second gravity component 4 rotates 90 degrees or 270 degrees relative to the first gravity component 1, it can reduce the swaying and rotation of the first gravity component 1 when suspended.

[0041] The pull-down component 11 can be made of a high-strength and tensile-resistant material, with one end connected to the component being measured and the other end integrated inside the device. The function of the pull-down component 11 is to establish a deflection transmission path between the device and the component being measured.

[0042] The support mechanism is an auxiliary measuring component installed on the second gravity member 4. It can stably support the dial indicator 9 at a suitable height above the ground, ensuring that the dial indicator probe 10 maintains correct contact and vertical alignment with the detection point of the measured component (i.e., the bottom surface of the first gravity member 1).

[0043] Specifically, in actual testing, two deflection detection auxiliary devices are required for coordinated use: the first deflection detection auxiliary device is connected to the component being tested via a pull-down member 11, suspending the entire device in mid-air. At this time, the self-overlapping of the first gravity member 1 and the second gravity member 4 creates a constant downward pulling force, taut and straightening the pull-down member. The second deflection detection auxiliary device is placed horizontally on the ground, with a dial indicator 9 fixed to it using a support mechanism on the second gravity member 4. The dial indicator 9 is then raised to a suitable height, so that the dial indicator probe 10 vertically contacts the bottom surface of the first gravity member 1 in the first deflection detection auxiliary device. When the component being tested deforms under external load, the first deflection detection auxiliary device moves downward synchronously with the component's deformation. The dial indicator 9 detects the displacement change of the bottom surface of the first gravity member 1 through its probe, converting it into a readable value, thus realizing the detection of the component's deflection.

[0044] Compared with the prior art, the pull-down mechanism in this embodiment can guide the deformation of the component under test under external load to a lower position by tensioning and straightening it by its own weight, which is convenient for testing. The support mechanism provides reliable support for the dial gauge 9, improving the efficiency of the test. At the same time, the pull-down component 11 is set inside the first gravity component 1 and the support mechanism is set on the second gravity component 4. When it is necessary to test the deflection of the component under test, only the two deflection testing auxiliary devices need to be used together, without the need for complicated assembly and storage after the test, making the test more convenient and efficient.

[0045] Please see Figure 1 and Figure 2 In this embodiment, the first gravity component 1 is a steel ring, and the second gravity component 4 is a steel disk.

[0046] The steel ring is made of steel and has a ring structure with an internal cavity. The pull-down piece 11 is housed in the cavity.

[0047] The steel disc is made of the same material as the steel ring and has a disc-shaped structure. The steel disc is housed in a cavity and can rotate relative to the steel ring. This effectively reduces the shaking and rotation of the steel ring when it is suspended in the air, ensuring the accuracy of deflection detection.

[0048] Specifically, steel possesses high density and high strength physical properties, allowing it to provide greater weight within the same volume compared to other materials (such as plastics and aluminum alloys). This ensures that the self-weight of the first gravity component 1 and the second gravity component 4 can generate sufficient tension to keep the pull-down component taut and straight. Simultaneously, the annular structure of the first gravity component 1 (a steel ring) provides ample internal space to accommodate the pull-down component 11, the spiral spring 13, and the turntable 14. The combined structure of the first gravity component 1 and the second gravity component 4 is stable, preventing it from tipping over during placement, and provides a flat and regular mounting surface for the support mechanism, facilitating its rotation and fixation.

[0049] The ring and disc-shaped structures provide uniform force distribution and stable placement, reducing the impact of device shaking on the test results during the testing process. The first gravity component 1 and the second gravity component 4 are made of steel, which provides sufficient self-weight to meet the tension requirements of the pull-down component and prevent the support mechanism from overturning, while keeping the device volume under control. The ring structure of the steel ring provides ample space for the internal components (pull-down component 11, spiral spring 13 and turntable 14), and the flat surface of the steel disc (second gravity component 4) facilitates the installation of the support mechanism, making the overall structure of the device more compact and the layout more reasonable.

[0050] In some embodiments, the first gravity member 1 and the second gravity member 4 are an integral block structure with an internal cavity for accommodating the pull-down member 11 and a flat outer surface for mounting the magnetic base.

[0051] The first gravity component 1 and the second gravity component 4 are integral block structures, which are prone to rotation or swaying when the device is suspended, thus affecting the accuracy of deflection detection. Therefore, in this embodiment, it is preferable that the first gravity component 1 is a steel ring and the second gravity component 4 is a steel disk.

[0052] Please see Figure 2 In this embodiment, a turntable 14 and an elastic element are also included. The turntable 14 is rotatably disposed inside the first gravity element 1. The elastic element is disposed on the inner side of the turntable 14. The pull-down element 11 is disposed on the outer side of the turntable 14. One end of the elastic element is connected to the first gravity element 1, and the other end of the elastic element penetrates the inner wall of the turntable 14 and is connected to the other end of the pull-down element 11.

[0053] The turntable 14 is an annular component rotatably disposed inside the first gravity member 1. The turntable 14 may be made of plastic or other lightweight materials. An annular groove is provided on the outer side of the turntable 14, and the pull-down member 11 is wound and disposed in the annular groove.

[0054] The elastic element is a component with elastic reset function installed inside the turntable 14. One end of the elastic element is fixedly connected to the inner wall of the first gravity element 1, and the other end passes through the inner wall of the turntable 14 and is connected to the pull-down element 11. It can store elastic potential energy when the turntable 14 rotates, and release the potential energy to drive the turntable 14 to reset after the external force disappears.

[0055] Specifically, when it is necessary to connect the pull-down component 11 to the component being tested, the operator pulls the pull ring 12 to connect the pull-down component 11 to the component being tested. The pull-down component 11 drives the turntable 14 to rotate inside the first gravity component 1. At this time, the elastic element connected to the inside of the turntable 14 is stretched or twisted due to the rotation of the turntable 14 (such as the spiral spring 13 being twisted), gradually storing elastic potential energy. After the test is completed, the pull ring 12 is removed from the component being tested, the locking assembly 2 is released, the elastic element releases the stored elastic potential energy, drives the turntable 14 to rotate in the opposite direction, and the turntable 14 then pulls the pull-down component 11 back into the first gravity component 1, realizing the automatic storage of the pull-down component 11.

[0056] By setting up a turntable 14 and an elastic element, there is no need to manually retract the pull-down part 11. The elastic element drives the turntable 14 to rotate, which can complete the storage of the pull-down part 11, saving operation time, improving testing efficiency, and avoiding the problems of tangling and damage caused by the pull-down part 11 being placed randomly.

[0057] In this embodiment, the pull-down member 11 is a steel wire rope, and the elastic member is a spiral spring 13.

[0058] The steel wire rope is made of multiple twisted steel wires, and its tensile strength is much higher than that of ordinary ropes (such as nylon ropes). It can withstand the self-weight tension of the first gravity component 1 and the second gravity component 4 without breaking or elongating, ensuring the stable connection between the pull-down component 11 and the component being measured, and preventing the device from falling or the test from being interrupted due to the breakage of the pull-down component 11. At the same time, the steel wire rope has a certain degree of flexibility, which allows it to be flexibly wound as the turntable 14 rotates, making the winding and unwinding process smooth. It also has excellent wear resistance, is not easily worn due to friction during long-term use, and is not easily knotted, making it easy to store.

[0059] The spiral spring 13 is spiral-shaped and, when installed inside the turntable 14, has one end fixed to the first gravity member 1 and the other end penetrating the inner wall of the turntable 14 and connected to the pull-down member 11. When the turntable 14 rotates due to the pull-down member 11, the spiral spring 13 is twisted, storing torsional elastic potential energy. After the detection is completed, the spiral spring 13 returns to its original shape under the action of elastic force, driving the turntable 14 to rotate in the opposite direction, thereby winding the wire rope around the outside of the turntable 14 to achieve automatic storage. In addition, the return force of the spiral spring 13 is stable, which can ensure the consistency of each storage process and avoid messy storage of the wire rope.

[0060] Please see Figure 3 In this embodiment, the support mechanism includes a folding bracket 7 and a first clamp 8. The second gravity member 4 is provided with a receiving groove 5. The folding bracket 7 and the first clamp 8 are housed in the receiving groove 5. One end of the folding bracket 7 is rotatably connected to the inner wall of the receiving groove 5, and the other end of the folding bracket 7 is fixedly connected to the first clamp 8. The folding bracket 7 is used to lift the dial indicator 9 off the ground, and the first clamp 8 is used to fix the dial indicator 9.

[0061] The receiving slot 5 is a groove structure formed on the second gravity member 4, which is used to accommodate the folding bracket 7 and the first clamp 8, so that the two can be stored in it when not in use, avoiding taking up space or being damaged.

[0062] The folding bracket 7 is the main support component of the support mechanism. One end is rotatably connected to the inner wall of the receiving groove 5 of the second gravity component 4, and the other end is fixed to the first clamp 8. It can be folded and stored in the receiving groove 5. After unfolding, it can adjust the height and fix the dial indicator 9.

[0063] The first clamp 8 is a clamping component fixed to the end of the folding bracket 7, used to clamp the dial indicator 9 to prevent the dial indicator 9 from shifting or falling off during the test, and to ensure that the dial indicator probe 10 is perpendicular to the groove 15 on the bottom surface of the first gravity component 1.

[0064] Specifically, when the deflection detection auxiliary device is horizontally set on the ground, the operator rotates the folding bracket 7 out of the receiving groove 5 of the second gravity component 4, and adjusts the unfolding angle and height of the folding bracket 7 according to the detection requirements of the dial indicator 9; then the dial indicator 9 is placed in the first clamp 8, and the dial indicator 9 is fixed by the clamping structure of the first clamp 8 (such as bolt clamping, elastic clamping) to ensure that the dial indicator 9 is in a stable position; finally, the height of the folding bracket 7 is adjusted so that the dial indicator probe 10 is vertically abutted against the bottom groove 15 of the first gravity component 1, and the folding bracket 7 is locked at the same time to keep the height of the folding bracket 7 unchanged, so that the bracket is in a stable support state.

[0065] After the test is completed, release the first clamp 8 and remove the dial gauge 9. Fold the folding bracket 7 back into the receiving slot 5 to reduce the space occupied by the device and make it easy to carry and store.

[0066] The dimensions of the receiving slot 5 are adapted to the folding bracket 7 and the first clamp 8 to ensure that the two do not protrude from the surface of the second gravity component 4 after being stored, thus avoiding damage from collisions during transportation or storage.

[0067] Please see Figure 1 and Figure 2 In this embodiment, a locking assembly 2 is also included. The locking assembly 2 includes a rotating bolt, a fixed column, and a second clamp. The fixed column is fixed to the top of the first gravity member 1. The second clamp is disposed inside the fixed column. The rotating bolt is threadedly connected to the fixed column. The inner wall of the rotating bolt abuts against the outer wall of the second clamp.

[0068] The rotating bolt, the fixed column, and the second clamp are all provided with through holes, and the three through holes are coaxially arranged to allow the pull-down piece 11 to pass through.

[0069] The rotating bolt is a bolt component that is threadedly connected to the fixed column. It can move axially along the fixed column by rotating. The inner wall of the rotating bolt can abut against the outer wall of the second clamp, pushing the second clamp to clamp the pull-down member 11.

[0070] The fixed column is a columnar structure fixedly installed on the top of the first gravity member 1. The interior is a hollow structure to accommodate the second clamp, and the inner wall is provided with threads that are compatible with the rotating bolt.

[0071] The second clamp is a clamping component located inside the fixed column. The outer wall of one end of the second clamp can retract toward the axis under the push of the rotating bolt to clamp the pull-down piece 11 that passes through the fixed column.

[0072] The inner wall of the fixed column has a protruding structure in the horizontal direction, and the corresponding position of the second clamp has a recessed structure. The protrusion of the fixed column matches the recess on the second clamp, thereby connecting the second clamp to the inside of the fixed column and restricting the displacement of the second clamp in the vertical direction.

[0073] After one end of the pull-down member 11 is connected to the component being tested, in order to suspend the first gravity member 1 at a suitable height, it is necessary to lock the pull-down member 11 so that it can no longer be pulled out.

[0074] Specifically, the pull-down member 11 passes through the through hole on the second clamp. When the rotating bolt is tightened, the rotating bolt moves towards the second clamp, so that the inner wall of the rotating bolt abuts against the outer wall of the second clamp. The outer wall of one end of the second clamp contracts towards the axis of the through hole, thereby clamping the pull-down member 11 in the through hole, so that the pull-down member 11 is no longer pulled out, thereby ensuring that the first gravity member 1 is at a suitable height for easy detection.

[0075] The locking component 2 is set up so that the height of the first gravity component 1 can be flexibly adjusted to meet different test sites.

[0076] Please see Figure 2 In this embodiment, the second gravity member is provided with a rotating shaft, and the first gravity member is provided with a shaft hole adapted to the rotating shaft.

[0077] The shaft hole is a circular channel directly opened on the inner wall of the first gravity component, and the diameter of the shaft hole matches the outer diameter of the rotating shaft.

[0078] The rotating shaft is a shaft-shaped component fixedly mounted on the second gravity component. One end of the rotating shaft is telescopic to ensure that it can be smoothly installed in the shaft hole. Specifically, the telescopic function can be achieved by embedding a spring inside the rotating shaft; or, the telescopic function can be achieved by segmented nesting, that is, the rotating shaft is divided into a fixed section and a movable section, with the fixed section fixedly mounted on the second gravity component and the movable section nested on the fixed section.

[0079] The rotational connection is achieved through the fit between the shaft hole and the rotating shaft 6. The structure is simple, with few parts, which facilitates processing, manufacturing and assembly. At the same time, it reduces the failure rate of the device and extends its service life.

[0080] Please see Figure 1 , Figure 4 , Figure 5 and Figure 6 In this embodiment, a limiting component 3 is also included. The limiting component 3 includes a limiting outer frame and a limiting block. The limiting outer frame is disposed on the side wall of the first gravity member 1, and the limiting block is disposed on the inner side of the limiting outer frame and is slidably connected to the limiting outer frame.

[0081] The limiting frame is a frame-shaped structure fixedly installed on the side wall of the first gravity component 1. The interior is a hollow slide rail used to accommodate the limiting block and provide sliding guidance for it.

[0082] The limiting block is a block-shaped component located inside the limiting outer frame, with an opening on one side, allowing it to slide along the slide rail of the limiting outer frame. When the second gravity member 4 rotates 90 degrees or 270 degrees relative to the first gravity member 1, the limiting block slides out of the limiting outer frame, and the upper and lower ends of the second gravity member 4 are accommodated in the openings of the two limiting blocks to restrict the rotation of the second gravity member 4 and ensure that the shaking of the first gravity member 1 is minimized.

[0083] Please see Figure 2 In this embodiment, the bottom of the first gravity member 1 is provided with a groove 15.

[0084] The groove 15 is a recessed structure formed at the bottom of the first gravity member 1, and its position corresponds to the position of the dial indicator probe 10. It is circular in shape and is used to provide a positioning reference for the dial indicator probe 10.

[0085] Specifically, during the testing process, the dial indicator probe 10 needs to be placed against the bottom surface of the first gravity component 1 to detect the downward displacement distance of the first gravity component 1 (i.e., component deflection). If the bottom surface of the first gravity component 1 is a flat plane, the probe may slide due to slight shaking or vibration of the device, causing the contact position between the probe and the bottom surface of the first gravity component 1 to change, affecting the accuracy of the test data.

[0086] The groove 15 at the bottom of the first gravity component 1 matches the size of the dial indicator probe 10. When the dial indicator probe 10 comes into contact, the end of the dial indicator probe 10 can be embedded in the groove 15. The side wall of the groove 15 can restrict the horizontal movement of the dial indicator probe 10, ensuring that the dial indicator probe 10 always contacts the bottom surface of the first gravity component 1 in a fixed position.

[0087] In addition, the position of the groove 15 can be set at the center of the bottom of the first gravity component 1 according to the detection requirements, so as to ensure that the dial indicator probe 10 can be accurately aligned with the detection position of the component deflection.

[0088] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, a pull ring 12 is also included, which is connected to one end of the pull-down member 11.

[0089] The pull ring 12 is a ring-shaped component that is fixedly connected to one end of the pull-down member 11 that extends to the outside of the first gravity member 1. It is made of steel and is convenient for the operator to pull the pull-down member 11 by hand or with tools.

[0090] The pull ring 12 prevents the operator's hands from directly contacting the pull member 11 (such as a steel wire rope), thus preventing hand injuries or cuts and ensuring the operator's safety.

[0091] The pull ring 12 is connected to one end of the pull-down member 11, which can prevent the pull-down member 11 from being completely retracted into the first gravity member 1. The pull-down member 11 can be quickly pulled out for use without disassembling the device during the next operation, simplifying the operation process.

[0092] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this utility model, this should not limit the scope of patent protection of this utility model. Any technical solutions resulting from equivalent structural or procedural substitutions or modifications made based on the essential concept of this utility model and utilizing the content described in the text and drawings of this utility model, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this utility model.
